As the power of tests lies in their uses, language tests that are used to assess immigration eligibility exercise enormous power. Critical Language Testing calls for exposing the power of tests by examining the intentions of introducing tests and their effects on individuals and society, especially from the perspective of test-takers. This case study investigates the rationale for and impact of a particular language-in-migration policy in Australia, drawing on the experiences and perceptions of two skilled migration applicants. One of them was successful and the other unsuccessful, essentially on the ground of their language test results. Insights from the study challenge prevalent discourses about language tests and social integration, employability, economic efficiency, and national security. The article makes some policy recommendations for making the use of language tests more beneficial for immigrants and immigrant-receiving societies in a globalised world that has witnessed unprecedented flows of immigrants. 相似文献

This article describes an international study informed by a 3‐year‐long qualitative longitudinal project, which sought to discover the scholarly communication attitudes and behaviour of early career researchers (ECRs). Using a combination of small‐scale interviews and a larger‐scale survey, ECRs were questioned on their searching and reading behaviour, publishing practices, open data, and their use of social media. Questionnaire invitations were sent out via publisher lists, social media networks, university research networks, and specialist ECR membership organizations. One‐thousand and six‐hundred responses were received, with many coming from China, Russia, and Poland. Results showed that ECRs are adopting millennial‐facing tools/platforms, with Google, Google Scholar, social media, and smartphones becoming embedded in their scholarly activities. Open data sharing obtains widespread support but somewhat less practice. There are some differences in attitudes and behaviour according to age and subject specialism. 相似文献

The article reports on a study of the views and actions of nearly a hundred scholars – mostly academic researchers from four European countries and four disciplines – in regard to scholarly reputation in the Science 2.0 age. It specifically looks at the role that 'emerging reputational mechanisms and platforms are playing in building, maintaining, and showcasing scholarly reputation in the digital age. Popular examples of such platforms are ResearchGate and Academia.edu . Data were obtained through one‐to‐one interviews and focus groups, supported by desk research. The main findings were: (a) it is early days and uptake is light and patchy with platforms largely used for non‐reputational purposes, such as sharing documents; (b) most users were passive and did not fully engage with the social aspects of the platforms; (c) the reputational focus was very much on just one scholarly activity (research), on just two outputs of that activity (publications and conferences) and one measurement of that activity (citations), but there are the stirrings of change; (d) young researchers are set to profit most from the emerging platforms. 相似文献

Adopting an intradisciplinary perspective, this article evaluates the information-seeking behavior of academics from different subfields of physics and astronomy. It investigates the effect of interdisciplinarity (reliance on the literature of other subjects) and the scatter of literature on two aspects of the information-seeking behavior: methods used for keeping up-to-date and for identifying articles. To this end a survey of 114 PhD students and staff at the Department of Physics and Astronomy at the University College London was carried out. The findings showed that the subfields that are more interdisciplinary or have a more scattered literature are more likely to use general search facilities for finding information. The study also showed that cross-disciplinary use of the literature is not necessarily an indicator of scattered literature. The study reveals intradisciplinary differences among physicists and astronomers in terms of their information-seeking behavior and highlights the risk of overlooking the characteristics of information-seeking behavior of specialized subject communities by focusing on very broad subject categories. 相似文献

Endothelial cell death due to increased reactive oxygen species(ROS) may contribute to the initial endothelial injury,which promotes atherosclerotic lesion formation.Piper sarmentosum(PS),a natural product,has been shown to have an antioxidant property,which is hypothesized to inhibit production of ROS and prevent cell injury.Thus,the present study was designed to determine the effects of PS on the hydrogen peroxide(H2O2)-induced oxidative cell damage in cultured human umbilical vein endothelial cells(HUVECs).In this experiment,HUVECs were obtained by collagenase perfusion of the large vein in the umbilical cord and cultured in medium M200 supplemented with low serum growth supplementation(LSGS).HUVECs were treated with various concentrations of H2O2(0-1000 μmol/L) and it was observed that 180 μmol/L H2O2 reduced cell viability by 50% as denoted by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) assay.Using the above concentration as the positive control,the H2O2-induced HUVECs were concomitantly treated with various concentrations(100,150,250 and 300 μg/ml) of three different extracts(aqueous,methanol and hexane) of PS.Malondialdehyde(MDA),superoxide dismutase(SOD),catalase(CAT) and glutathione peroxidase(GPX) levels showed a significant increase(P0.05) in HUVECs compared to the negative control.However,PS extracts showed a protective effect on HUVECs from H2O2-induced cell apoptosis with a significant reduction in MDA,SOD,CAT and GPX levels(P0.05).Furthermore,PS had exhibited ferric reducing antioxidant power with its high phenolic content.Hence,it was concluded that PS plays a beneficial role in reducing oxidative stress in H2O2-induced HUVECs. 相似文献

This research paper is a pilot study that investigated the suitability of adopting an automated balanced scorecard for managing
and measuring the performance excellence of academic staffs in the higher education setting. A comprehensive study of related
literature with requirements elicited from the target population in a selected premier university in Malaysia through document
analysis, interviews and survey questionnaires provided the foundation for the system development. By adopting the balanced
scorecard, the proposed system provided a means for top down alignment of organisational objectives while creating a medium
of communication between the lecturers and management. Though the method suggested in this study primarily focuses on the
academic staff, it addresses the lack of a representative form of performance measurement for lecturers that accommodates
the complexities of the profession while providing the potential adoption of an unconventional method to encourage excellence
and development amongst all levels of employees in the industry. 相似文献

Collaboration in science is a process in which two or more authors share their ideas, resources and data to create a joint work. This research compares coauthorship networks of Iranian articles in library and information science (LIS), psychology (PSY), management (MNG), and economics (ECO) in the ISI Web of Knowledge database during 2000–2009, and uses network analysis for the visualization of coauthorship networks. Data include all articles with at least one Iranian author and indexed in ISI's Social Science Citation Index (SSCI) for the fields of LIS, PSY, MNG, and ECO. Indicators such as the Collaborative Index (CI), Degree of Collaboration (DC) and Collaboration Coefficient (CC) were calculated for each discipline. Results show that two or three authors were the most common number of authors per paper, and authors of PSY tended to have more multi-authored articles, compared to the other disciplines. LIS had the lowest rank regarding CC. MNG had the densest coauthorship network, and PSY had the sparsest. Iranian authors in the field of PSY mostly collaborated with those in the U.S., while LIS and MNG authors tended to collaborate with U.K. authors, and ECO authors tended to collaborate with Canadians. 相似文献

The paper identifies changes that have occurred in the Web environment over the last decade which have gradually rendered server logs, once the preeminent source of intelligence on usage and information‐seeking behaviour, an ineffective, impractical, and uneconomic resource. It also looks at the implications of these changes for information professionals and publishers who have come to rely on this data to understand the behaviour of clients and customers in the virtual environment. Ubiquitous and expanding, Google Analytics generates statistics about a website's traffic and traffic sources, albeit from a marketers' perspective, is evaluated as a possible replacement; something which might plug the user knowledge gap which is worryingly opening up, or maybe even, put us in a better position overall. The paper is built on the knowledge and experience of evaluating server logs for more than a decade, mostly for publishers and libraries, and also on two recent projects where server log analysis was supplemented with Google Analytics. 相似文献

After two-years of repeat interviewing early career sciences/social sciences researchers from around the world about their work life and scholarly communications in pandemic-times, the Harbingers-2 project is in a position to release quantitative data on the pandemic's overall impact. The data comes from around 50 questions asked in the third and final round of interviews with 147 early career researchers (ECRs), which had a codifiable element to them (such as yes, no, do not know). The 19 scholarly topics covered include: pandemic-related research; research funding; changes to the workplace/working from home; pandemic-incurred stress and anxiety; teaching; employment security; career progression; mentoring; assessment (including metrics); collaboration; searching/finding information; ethics; networking; informal communication; publishing; sharing; pre-prints; outreach; and scholarly transformations. The main findings are that in six broad aspects of ECRs' work-life and scholarly behaviour, more than 50% of ECRs were impacted by the pandemic, with remote teaching having the greatest impact. By way of comparison, in another six aspects there was little change, least of all when it came to sharing activities. Among the countries studied, Malaysia stood out as being the most impacted, and of the disciplines it was the medical sciences and the soft social sciences most impacted. 相似文献
